摘　　要：为了鉴定新型棉花化控调节剂‘棉太金’与‘全精控’的作用效果,并确定其在辽河流域棉区适宜的应用方法,采用对比法,以棉花品种‘辽棉30号’为试验材料,利用‘棉太金’、‘全精控’、缩节胺(DPC)、矮壮素进行化控处理,比较分析了植株的发育进程、成铃分布、棉铃干物质分配、产量及其构成因素、以及纤维品质。研究结果表明:‘棉太金’和‘全精控’作为新型棉花生长调节剂,能够帮助棉花塑造合理株型、协调成铃分布、优化棉铃干物质分配、防止早衰、提高产量,同时对纤维品质无不良影响,可以在辽河流域棉区推广应用。但是其用法和用量应根据生产实际进行调整。一般建议不宜早控,前期(蕾期到初花期,6月中旬—7月上旬)轻控,中期(盛花期到铃花期,7月中旬—下旬)适控,后期(铃花期,7月下旬到8月上旬)重控。The study aims to identify the effect of new cotton chemical regulators‘Miantaijin＇and‘Quanjingkong＇, and confirm their suitable application method in Liaohe basin. A comparison text wasconducted to study the development process, boll distribution, boll biomass distribution, yield and itscomponents, and fiber quality of‘Liaomian 30＇under the treatment of‘Miantaijin＇,‘Quanjingkong＇,mepiquat chloride（DPC） and chlormequat chloride. The results showed that the new cotton chemical regulators‘Miantaijn＇and‘Quanjingkong＇could help to shape the reasonable plant structure, coordinate bolldistribution, optimize boll biomass distribution, prevent premature senility, increase yield, while had noadverse effect on fiber quality, therefore, the two regulators could be popularized and applied in Liaohe basin.However, the usage and dosage should be adjusted according to the production practice. Generally, too earlyregulation was not recommended, the regulation should be controlled lightly in the early stage（bud stage toflowering stage, mid-June to early July）, adequately in the medium stage（flowering stage to boll florescence,mid-July to late July）, and strongly in the late stage（boll florescence, late July to early August）.
